From your output, it's clear that you are trying to run the "slideshow" experiment script with the TRACKERTYPE set to eyelink. This will not work, because you say you do not have an EyeLink, and because (as the error message indicates) you have not installed the library pylink (which would be required for working with an EyeLink tracker.

Finally, you are also using the wrong software. What you are running is an experiment script, but what you say you want to do is use PyGaze Analyser functionality. For this, I would like to refer you to your other question, where you have been pointed to example gaze data files.

PS. In both this and one of your other questions, you have posted a question on 2 January, and followed this up with a request to urgently reply on 3 January. Everyone here volunteers there time next to at least a fulltime job, which makes it unlikely that we respond very quickly.
